Physical activity improves learning and hippocampal neurogenesis. It is unknown whether compounds that increase endurance in muscle also enhance cognition. We investigated the effects of endurance factors, peroxisome proliferator-activated receptor δ agonist GW501516 and AICAR, activator of AMP-activated protein kinase on memory and neurogenesis. Mice were injected with GW for 7 d or AICAR for 7 or 14 d. Two weeks thereafter mice were tested in the Morris water maze. AICAR (7 d) and GW improved spatial memory. Moreover, AICAR significantly, and GW modestly, elevated dentate gyrus neurogenesis. Thus, pharmacological activation of skeletal muscle may mediate cognitive effects.

Introduction: Impaired physical fitness is a possible late effect among adult survivors of childhood cancer (ASCC). Our study describes lower body muscular strength and endurance among ASCC using the 1-minute sit-to-stand (1-min STS) test, compares them with the general population, identifies risk factors, and describes changes over time.Methods: In a prospective multicenter cohort study, we invited ASCC ≥18 years of age at study, diagnosed between ages 0-20 treated in five pediatric oncology centers across Switzerland from 1976-2017 who survived ≥5 years for a 1-min STS test.

Curcumin is known for its potential health benefits; however, the evidence remains inconclusive regarding its necessity as a supplement for athletes during the preparatory phase of training. This study aimed to assess the effect of 6-week curcumin supplementation at a dose of 2g/day on selected inflammatory markers, blood count, and brain-derived neurotropic factor (BDNF) levels in middle-aged amateur long-distance runners during the preparatory period of a macrocycle. Thirty runners were randomly assigned to either a curcumin-supplemented group (CUR, n = 15) or a placebo group (PLA, n = 15).

Background: Prior research indicates that engaging in physical activity during chemotherapy can positively influence both physical and psychological parameters in individuals with hematological neoplasms. However, the most effective type, level, intensity, and frequency of exercise remains unclear.
Patients And Methods: We enrolled 53 patients to a clinical trial assessing a partly supervised hybrid training program including both strength and endurance components, commencing at onset of induction therapy (T0) for hematological malignancies, including AML (n = 29), ALL (n = 5), and NHL (n = 19).

Background: Chronic obstructive pulmonary disease (COPD) is characterized by airway inflammation, airflow limitation, reduced health-related quality of life (HRQL), and exercise intolerance. Pulmonary rehabilitation (PR) is essential for COPD management, but outcomes may be influenced by individual physiological factors. Cardiopulmonary exercise testing (CPET) measures oxygen pulse (O2P), an indicator of stroke volume, yet the impact of baseline O2P on PR effectiveness remains unclear.

Haematological malignancies and their treatment regimens often lead to various complications that impair patients' physical functioning. This study aimed to assess the level of physical activity and exercise capacity in patients with haematological malignancies who were qualified for haematopoietic stem cell transplantation (HSCT). A prospective, single-centre study was conducted on patients with haematological malignancies qualified for HSCT (study group, = 103) and a cohort of healthy volunteers (reference group, = 100).
